November 2022 Xchange

The November 2022 Xchange highlights just some of the contributions that have recently been published on ChemEd X. We hope you will take a moment to check in and see what you may have missed. 


Nora Walsh outlines the interactive notebook pages she uses for her unit on Bonding. All of the documents and foldables are available for download.  


The theme for National Chemistry Week 2022, observed October 16-22, was “Fabulous Fibers: The Chemistry of Fabrics”. A visit to Natural Fiber Welding, Inc. in Peoria, IL, revealed how that company is using ionic liquids to solvent weld cellulose fibers together to produce more durable yarn which can then be made into more durable fabric. The production method and “greenness” of the product is discussed, from the cellulose itself to the recycling of the solution used in the welding process. Macroscopic demonstrations of the fiber solvent welding process are also described. 


The use of multiple representations helps to characterize students' understandings and their misconceptions. Stacey Lowery Bretz shared multiple resources and strategies for using them in her ChemEd X Talk. The summary article includes a recording of the session.


From the archives - This article was originally published in August 2017. Teaching students the proportional reasoning skills needed for stoichiometry doesn’t have to be that daunting. By adjusting how your students talk about stoichiometry, you will adjust how they think about it; eventually, they’ll proportionally reason in a more effective manner.


Heartburn is a very common ailment. Many people rely on antacids such as Tums®, Rolaids®, or Milk of Magnesia to settle their stomachs, but have you ever wondered how those antacids work? 


Explore how small the stuff that makes up matter is and consider what those tiny particles are doing in this engaging activity.


Part 2 includes further anthocyanin experiments to make a connection between the food we eat and the chemical principles that are employed to ensure that canned foodstuffs can be preserved properly.


This demonstration lays the foundation for what science is all about: proper experiments, properly carried out, properly interpreted.


Students become familiar with the elements and their abbreviations, as well as their location on the periodic table while engaging in this series of crossword puzzles.
